Twelve-year outcomes of watchful waiting versus surgery of mildly symptomatic or asymptomatic inguinal hernia in men aged 50 years and older: a randomised controlled trial.

Background: Inguinal hernia belongs to the most common surgical pathology worldwide. Approximately, one third is asymptomatic. The value of watchful waiting (WW) in patients with asymptomatic or mildly symptomatic inguinal hernia has been established in a few randomised controlled trials (RCTs).

Predicting Mortality Within 90 Days of First Intervention in Patients With Left-Sided Obstructive Colon Cancer.

Background: Acute resection for left-sided obstructive colon carcinoma is thought to be associated with a higher mortality risk than a bridge-to-surgery approach using decompressing stoma or self-expandable metal stent, but prediction models are lacking.

Objective: This study aimed to determine the influence of treatment strategy on mortality within 90 days from the first intervention in patients presenting with left-sided obstructive colon carcinoma.

Design: This was a national multicenter cohort study that used data from a prospective national audit.

Lateral Pelvic Lymph Node Metastases in Rectal Cancer: A Systematic Review.

Background: Synchronous lateral pelvic lymph node (LPLN) involvement occurs in a significant number of patients with rectal cancer. The aim of this study is to determine the rate of LPLN metastases in rectal cancer patients with LPLN suspicious for metastases (LPLNSM) on pretreatment imaging, treated with neoadjuvant chemoradiotherapy (nCRT). Additionally, the influence of LPLN responsiveness to nCRT as determined by post-nCRT restaging scan was investigated.

Stereotactic Pelvic Navigation With Augmented Reality for Transanal Total Mesorectal Excision.

Introduction: Technical difficulty and unfamiliar surgical anatomy are the main challenges in transanal total mesorectal excision. Precise 3-dimensional real-time image guidance may facilitate the safety, accuracy, and efficiency of transanal total mesorectal excision.

Technique: A preoperative CT was obtained with 10 skin fiducials and further processed to emphasize the border of the anatomical structure by 3-dimensional modeling and pelvic organ segmentation.
